Anyone interested in aluminum hubs for 70-78 Z ?

[Guest Zachb55]

oops, sorry bout that Juan, i knew your name but just forgot while posting, i dont know the process of pressing in the bearings but i would be concerned as well about replacing them in the future, would this be guaranteed trouble or is it just somewhat risky with the aluminum?

I think The offset should be changed to about a +30-35 mm offset this would allow the use of modern wheels without a spacer that most of us converting to five lug have to run. The main reason to convert to 5 lug is to be able to run the modern wide wheels made for mustangs, supras, 300zx's,rx7's, etc. The 0 offset im afraid would still leave almost the same limits on wheel selection still requiring custom offsets. Hopefully more guys will chime in here. Im also curious about changing out the bearings will this be a problem. Dont want to mess up anything. Also in reference to the az link. He is just running standard wheel hubs. Those aluminum hubs you were talking about are just hats. Juan (jay-z) also makes these soon to be in a five lug pattern.

hey guys,

 

I've got a set of aluminum hubs on my car ot work with SFZ 12" vented rotors, they are the same bolt pattern at stock. SFZ made my hubs. I believe they came in at 4.5 lbs each, and they are swain BBE coated. At anyrate i think aluminum hubs are a great idea for these aftermarket brake kits and wheels. My input though is on the bearings: My hubs have the exact same deminsions as stock on the inside and have pressed in steel bearing races, everthing fits up the same as stock and there is no wear issue with the aluminum.

 

Here's a few pics.

 

those are metal shavings in the bearing section, just hadn't cleaen it out yet..

Is that hub and hat one piece? Looks real good. Can we ask you paid for those hubs/hats.

 

Whatever you want you got it. I just think there are some people who would like to run aluminum stock hubs for weight savings at least and their current brake system. Jared, I don't think I will have to run a 5 lug setup with this. Should I do these in a 4 or 5 rotor pattern(the backside of the hub). It looks like I could configure here alot for all Z users

For 5 lug just vote on the pattern and + offset. Guys its your call. The bearings I can press in myself at the shop if you want to send in your bearings. When adding and removing races its important to take more care not to scour the aluminum race walls. I don't want to see anyone banging in races with 4 pound hammers and then whining what happened tot he aluminum is all I am saying. I can do it properly here if anyone needs assistance

Once I can see the number or interested people and Bolt pattern along with what offset beyond stock I can get a better #. No money down! Thanks Juan

Some more info on the hubs. They will be made from 6061 aluminum very strong and affordable.The same aluminum used in all my machining.

Like Austin pointed out there will be no issues with bearings. They will be machined to accept pressed in races.

For the threads I will add helicoils for rotor bolt down strength.

[ToplessZ]

Im putting in my vote for a 5 lug setup that would include the wilwood brakes and give a +30-35 mm offset. That would be all I needed for the fronts. then I just need a brake setup for the rears (edit: in a 5x4.5)

[Guest Zachb55]

my vote goes for what topless said^^^^

well here is the quote on 300zx hubs in the 5x4.5 Bolt circle with added offset that will work with 5 lug brakes. How much more offset does the 300zx hub need from its stock form to run your 5 lug rims?

$269.95 for 2 aluminum hubs.does not include studs,wheel bearings,and seals. I hope this sounds like a good price . I expect this to be available by late December thanks Juan

[ToplessZ]

IF we went our studs bearings and seals with the payment would you install them for us. Having a shop press makes those things go nicely as opposed to a 2x4 and a big hammer. I wouldnt know what to compare the price to really but that doesnt sounds bad to me.

[Guest Looking for apt in Alb Ny]

Id be happy to do that. Studs should cost about $20 or use used ones and bearing oh I don't know $50 or send your used one. I would insert them in for free before they leave. Also don't forget the 2 seals. I dont think you can compare this price to anything except for time and use of machining and material. if I were to just make 2 of these you are looking around $450+

 

 

I saw this auction on ebay. So I am making these right with more offset?What is the extra offset? Jared you sent your hub correct? I would have to make the front Wilwood brake hats for sure. Now I see why this all comes together. Then I have to make adapters for the rear.

[ToplessZ]

No I didnt send a hub as you said you already had one lined up. I would have to go out and source one.

[ToplessZ]

Wait a minute didnt you just say 269 for the 2 hubs is that the same thing you are talking about for 450?

[JMortensen]

Juan, don't make them like the 300ZX hub. You have a chance to fix the dust seal issue while you're doing this. The 300 hubs are too narrow and don't fit quite right on the inside. Get a 240 hub and a 300 hub. Make the races and bearings and seal fit like the 240, but with the 300 lug pattern.

 

My $.02,

 

Jon

[Sparky]

I dont know what Yall are talking about when you say you cant find a decent rim in a 5 bolt 0 offset pattern. your possibilities when going 5 lug are almost endless. I personally love the deep dish look, And would prefere it to stay that way.

 

also, For those of us that are doing the front first, to have to buy two different rim offsets for the front, then buy two different rims for the rear, seems like a bit of a pain. Sure I could correct it with a spacer or adapter, But then whats the point of buying lite weight hubs, if im just going to add weight to it in order to correct something we could have addressed in the first place. having two different offsets on a car will look stupid.

 

And please, If My information is incorrect, somebody feel free to chime in and set things straight.

 

also, I would like to thank juan for taking the time to get all these things going for us. he is an asset to the Z community and we should all take the time to thank him for his work.

[Guest Looking for apt in Alb Ny]

Jared,Sorry I was getting confused with another member that has sent me a hub.

 

So make it to the 300zx dimensions but internally to the 280z hub correct. Ill see what difference there is inside the bearing race area between the 2 hubs.

Now what about extra offset. I didn't hear anyone state how much more should be added to the hub. I was told 35-38mm. Is this additional offset off the 280z or 300zx hub? I would think the 280 hub.

 

When I mean made to the 300zx specs I need to make sure my 5 lug Wilwood works with other Zers who are running steel hubs and would like to convert to aluminum in the near future. The hub will not be pentagon shaped or any silly casting Nissan put into the hubs. Just the necessary stuff such as the center bore,race areas on each end, 5 x 4.5 bolt pattern (made to fit the stud real snug), and the hat or rotor bolt pattern on the inside. Don't worry guys I got you covered on this. Juan

[ToplessZ]

Yes the 35-38mm would be on top of the 280z original offset. This is what the offset would change to if using a 300zx hub. As you stated I concur that simple is better in this part. It will keep cost down and ease up the manufacturing process. The only thing is I would try to keep it about 35mm. I dont know if more than that might start eliminating wheel options or not. I think that would be about right. Hopefully some other guys will comment. As far as having a different offset front and rear juan did say he would be working on something for the rears possibly. As far as deep dish goes thats a matter of taste. I will be running volk rims with a pretty big dish but they still have the newer offset pattern. They just happen to be really wide!!! These type of rims are made for supras 300z's etc... Also the new mustang rims. There are alot of us running these with the 300zx hub already and a spacer in the rear. Only disadvantage is the dust seal not fitting and having a heavier part. Juan's work would be clearing up both of those issues. Im all for getting rid of the spacer in the rear. Although I have a full set of 4 to 5 lug spacers already, Im a little leary on using them.

if link doesnt work they are 5 lug rear hubs from a 240sx. bid is at $250 and 5 days stil left.

Jared, could you plese post pictures of the 5 lug adapters. Why would you be weary of using them. you plan on running 275 tires with them? A lot of abuse I would imagine.

I guess we can compare the hubs to that in price and they will be aluminum. Hmm Are they making conversion hubs for the 240sx users (to 5 lug) thanks Juan

[ToplessZ]

actually Im planning on running a 335 tire and a significant amount of torque and I dont want longevity problems. Ill work on getting pics of those 5 lug adapters but its probably going to take some time.

[Guest Looking for apt in Alb Ny]

Hello Fellow Zer's

 

I have come to a decision of making an end to the Tb 240sx Spacers, 300zx vented rotors spacers, and Barb and O ring fuel rails. I do have some items left if interested at discount prices. The items listed on eBay are what is left as well.

The reason is it has been difficult moving towards new items. The time needed to machine the above listed items takes away from you name it

5 lug aluminum hubs with their brake package and well as creating universal applications.

 

I would also like to let you know that I am accepting a 25% down deposit on 5 lug aluminum hubs for 70-78. Here are the prices for Hubs alone and their needed brake setups.

If I can get 10*25% down payments or 3 completely paid items production start this January. I don't need the whole hunk of change yet but this should cover material cost and some coffee expenses!

 

If you plan on ordering in the near future please email me JSK@jskinnovations.com so I can get an idea on how many to machine and not over machine.

 

5x4.5 bolt pattern Aluminum hubs with an extended 35mm offset - $269.95

Hubs will be based on 280z design but with 300zx 5 lug geometry.

 

5 lug hats with 7 inch by 8 bolt pattern and 3/8 steel brackets to work with JSK Aluminum 5 lug hubs or stock existing 300zx hubs (on 70-78 only) - $269.95

 

Much work involved these prices are a steal.

 

Combine both for a 15% savings!

comes to $459.92

[100]

Yes Yes Yes.

 

All I know is I want big brakes at all 4 corners and 5 lugs at all 4 corners. 5x4.5 at 0 offset for 73 240z. You should come up with a complete package kinda like arizona.

 

Also own a 93 240sx s13 and wnat the same thing big brakes and 5 lugs at all 4 corners. 5x4.5

 

They make 5 lugs for the 240sx Attain from Japan expensive but very nice.

 

If I was you I would concentrate all my efforts on big brakes and 5 lugs for thes 2 cars, you will be bombed with buyers.

Are these going to have some corny name etched all over them like your other products?
